This paper introduces the progress on X-ray laser investigations in CAEP,including the experiments of X-ray lasers gain of Ne-like Ge pumped by electron-collision excitation, double-pass amplification of X-ray laser, low enery double-pulse driving and X-raylasers pumped by other schemes. The attentions are paid to the experimental principles, designs and results. Some suggestions of future investigations are also discussed.
